ROMULUS, Mich. – The previous two Stanley Cup champions are meeting in the playoffs for the third time since the NHL expanded four decades ago.

Perhaps fittingly, a Game 7 is necessary.

The Ducks and Detroit Red Wings have pushed their Western Conference semifinal series to the limit just as Edmonton and Calgary did in 1991 and Montreal and Boston did in 1971 in the last two matchups of Cup winners.

“It should be exciting,” Red Wings coach Mike Babcock said Wednesday when the team plane landed in rain on a miserable evening that matched its mood following a 2-1 loss. “Game 7s are always a lot of fun.

“It’s a good opportunity for us. We played all year to have home-ice advantage.”

The second-seeded Red Wings will face the eighth-seeded Ducks tonight at home, hoping to follow a trend.

Entering Wednesday’s night’s Pittsburgh-Washington finale, home teams have won 63 percent of Game 7s since 1939.

Two of the exceptions, though, happened when the Oilers defeated the Flames in overtime and the Canadiens beat the Bruins by two goals as road teams in matchups of previous champions.

This postseason, the Ducks have proven they can win anywhere and their confidence has grown.

“Everyone is believing we can beat this team,” Anaheim star Ryan Getzlaf said.

Anaheim won Game 2 at Joe Louis Arena in triple overtime and opened the playoffs with two road wins against the top-seeded San Jose Sharks.
